The numerical control equipment of 21 century will be have certain intelligentized system, and intelligentized content is included in the various aspects in digital control system: for pursuing the intellectuality of working (machining) efficiency and crudy aspect, as the Self Adaptive Control of process, technological parameter generates automatically; For improving driveability and using intellectuality easy to connect, as the self adaptation computing of feedforward control, the parameter of electric machine, automatically identification load selected model, Self-tuning System etc. automatically; Simplify the intellectuality of programming, the aspect that simplifies the operation, as intelligentized automated programming, intelligentized man-machine interface etc.; Also have intelligent diagnostics, the content of intelligent monitoring aspect, the diagnosis facilitating system and maintenance etc.Intelligence is ground consulting and is pointed out, at present, the development of Digit Control Machine Tool is maked rapid progress, and high speed, high precision int, Composite, intellectuality, Opening, parallel drive, networking, extramalization, greenization have become the trend and direction of Development of CNC Machine Tools.
The main contents of Turning Process on NC Lathe: analyze processing route, procedure of processing, fixture scheme, evaluation, select cutter, coding.Lathe in machining program and engine lathe technological procedure have bigger difference, and the content related to is also wider.Lathe in machining program not only will comprise the technical process of part, but also will comprise cutting data, cutting line, the motion process of tool dimension and lathe.Therefore, require that the clamping method of programming personnel to the performance of numerically controlled lathe, feature, motion mode, tooling system, cutting specification and workpiece is all very familiar.The quality of process program not only can affect the performance of lathe efficiency, and will directly have influence on the crudy of part.Complete Turning Process on NC Lathe mainly comprises following content: the drawing analyzing part to be processed, specifies operation processing content and technical requirement.Determine the processing scheme of part, formulate numerical control processing technology route.As dividing step, arrange processing sequence, process is connected with non NC machining operation.The design of manufacturing procedure.As chosen the positioning datum of part, determination, work step division, the cutting tool choice of fixture scheme and determining cutting data etc.The adjustment of nc program.As chosen tool setting point and tool changing point, determining cutter compensation and determine processing route etc.
The hard car of current part bevelled carbon steel product needed secondary, the numerical control turning method adopted during the hard car of this series products, by programme-control facing, inclined-plane, chamfering, and cutter head is formed by artificial grinding, during hard car, cutter head is easy to wear, needs staff constantly to repair cutter head, and this numerical control turning method speed is slow, and production and processing is complicated, processing cost increases, and the amount of labour is large.
Summary of the invention
In order to solve the problem, the present invention proposes a kind of processing method of numerical control turning radiused ramp chamfering, simplicity of design, process easy to use, provide a kind of novel cutter to coordinate ripe processing method, solve the flow process of complex operations, save labour, reduce production and processing cost.
In order to reach foregoing invention object, the present invention proposes following technical scheme:
A kind of process tool of numerical control turning radiused ramp chamfering, described cutter comprises handle of a knife and cutter head, cutter head is welded on handle of a knife, described cutter head comprises straight line cutter head and semicircular arc cutter head, straight line cutter head and semicircle cutter head are connected to form one, and the turning tooth shape shape on cutter head is that straight line cutter head and semicircle cutter head combine the curve shape formed.
The turning tooth shape shape of described cutter is by digital control wire-electrode cutting once one excision forming.
Use the process tool of numerical control turning radiused ramp chamfering to carry out the processing method of numerical control turning radiused ramp chamfering, its concrete steps are:
1) when determining numerical control turning curve, the turning circular arc chamfer part of needs is defined as a build-up curve, and build-up curve is divided into three sections, and wherein a section is a plane, and another section is easement curve face, and final stage is plane; Two ends, easement curve face smoothly connect with end flat;
2) the process tool geomery of needs is calculated according to build-up curve, cutter is put on nc wire-cutting, straight line program carries out geomery setting, according to the geomery that the geomery of programming needs cutter initial cutting processing, and an excision forming;
3) on the fixture of the tool-holder processed on numerical control turning lathe, treating that the workpiece clamp of numerical control turning radiused ramp chamfering is in chuck, cutter and workpiece are positioned clamping, and start-up routine carries out the turnery processing of build-up curve;
4) after turning completes, workpiece straight forming.
Advantage of the present invention is that cutter structure design is ingenious, solves numerical control program complex operations, programme-control facing, inclined-plane and chamfering, adopt this workpiece processing tool shaping with regard to a turnery processing, the above-mentioned three process of disposable processing, controls without the need to complicated process, and cutter adopts Linear cut shaping, rational in infrastructure, blade firm and durable, not fragile, save labour, reduce processing cost, improve production efficiency simultaneously.
